Chain Pain (5e Spell)

From D&D Wiki

A dark lightning bolt leaps from your finger towards the target, inducing pain and leaping towards another nearby creature. A creature that you target with this spell make a Constitution saving throw. On a failed save, the targets take 5d6 necrotic damage and is stunned until the end of your next turn. The bolt then leaps to a second creature of your choice within 10 feet of the target, which must then succeed on the same save and suffer the same effects, though the bolt cannot travel to a third creature. On a successful save, the target takes half as much damage and the bolt doesn't leap to another target.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, increase the necrotic damage dealt by 2d6 for each slot level above 6th.
